. IMPROVEMENT IN 'CAR-SPRINGS,

Specification forming part of Letters Patent No. 36,5l3, dated October QS, 1%62.

To all whom it may concern:

Be it known that I, RICHARD Voss, of the city., county, and State et' New York, have invented a new and Improved Car-Spring; and

I do hereby declare that the following is a full and exact description thereof, reference being" had to the accompanying drawings, which form a part of this specification.

Figure 1 is a top view of said spring; Fig.

2, aside view; Fig. 3, a section in the line t `of Fig..1; and Figs. 4 and 5 are views of detached portionsof said spring.

My improved car -spring is composed of one or more series orclusters of light volute l suitable protecting-casing, inl the manner `rep*` resented in the accompanying drawings.

I construct my improved car-spring of the above-mentioned parts inthe following malt ner, viz: One of the layers E is first placed in the bottom of the lower portion, I5, of the casing. Then a metallic plate, E', o f correspending shape to the said elastic layer, and which has four tc-atshaped projections, L k', rising from its upper surface, is placed upon the said elastic layer II. `Then four volute springs, I I I I, are placed upon the said plate E', and in such positions as to cause the said springs to each embraceone of the projections k of said plate, as shown in Fig. 3. Then I place the metallic plate D n pon the before-mentioned springs I I, the said plate having four annular 4ilanges descending from its under surface, which embrace the upper ends of the said springs I I. Then I place nponthemetal-lie plate D a layer II, and then upon the said layer I place the `metallic plate 1l,the said `layer H being held in its po etion between the said plates by means of the pins j' j, which descend from the plate F. and

pass through apertures inthe layer I-I, and also thrpngh corresponding apertures in the plate D",- as shown in Fig. '3. Then upon Athe metallic plate E, I place another set of four volute springs I I, the said `springs being kept in position by the four projections k lr, which rise from thesaid plate, and which are respectively embraced by the said springs.

This lastmentioned set of springs is covered and embraced by the metallic plate D, which exactly corresponds in shape with the beforementioned plate 1)', and between the said metallic plate D and the inner surface of the head of the portion A of the casing I place another elastic layer H.- The respective parts A and B of-the casing of Iny improved 'can spring are of such a shape that one of said` parts is allowed to slide freely upon the other,

and the separation of said parts is prevented by the central screwfbolt.

In the construction of my said improved car-spring I do not intend to limit myself to the use of any precise -number of Yvolute springs I I in each cluster; nor do I intend .to

limit myself to the use of any precise number of clusters of volute springs in the construction of my said improved earspring. My.

object is 'to form a car-spring of great power within their casing by means of the metallic plates I) D and E E and the pins j j, In the manner represented in the accompanying drawings.

, Havingthus fully described my improved car-spring, what I claim therein as new, and

`desire to secure by Letters Patent, is

rIhe arrangement, within a suitable casing, of one or more series of volutcsprings,1 I, and

a number of layers, H H, of some elastically` yielding substance, when the requisite number of metallic combining and steadying plates I) E are arranged with the said volute .springs and elastically-yiclding layers in the manner represented by the accompanying' drawings and herein particularly set forth.

The above specification of mynew and improved car-spring signed and witnessed this 22d day oi' December, 18,60.
